The total cost of the meal is $37.80
Given:
Food bill = $30
tip = 20%
sales tax = 6%
Tip and sales tax must be based on the food bill.
Tip = $30 x 20% = $6
Sales Tax = $30 x 6% = $1.80
Food bill : 30.00
Tip 6.00
Sales tax <u> 1.80</u>
Total cost 37.80
One jug would be full and the other jug would half to be 1/4
Since y=-1 when x=0 and we can write the equation (we'll turn it into an inequality later) as y=mx-1 from y=mx+b by plugging (0,1) in. Next, y equals 2 when x=1, so we plug those in to get 2=m*1-1. Adding 1 to both sides, we get 3=m, making our equation y=3x-1 (since y and x stay variables). Lastly, we turn it into an inequality, It seems to be inclusive to the line, so it's either
3x-1≤y or 3x-1≥y. Finding a random point in the inequality (4, 1), we plug it in to get 12-1=11, which is clearly larger than 1, so we get 3x-1≥y.
Your answer is -4 !!
step 1.) write the number in exponential form with the base of
step 2.) reduce the index of the radical and exponent with
step 3.) with all that being said your answer would be -4 :D
